Mistmoth Dragons take refuge in the unknown. As the mature, they are less and less communicative of their feelings and needs, so enjoy the time with your toddler Mistmoth, and don't worry when it expresses less later in life.
Mistmoth Dragons might be less expressive than other dragons, but they take their relationships more seriously. As the keepers of secret knowledge, to them, knowing is more powerful than showing, even with love.
Adult Mistmoth Dragons begin to disappear from their homes from time to time, as they scout their surroundings for hidden caverns, ancient ruins and other secret locations. They are happiest when they find something no one else has found.
Epic Form Mistmoth Dragons are not credited with great discoveries, as they only ever share their secrets on the last day of their lives, to the person they trust most. That person then gets to retrace the Dragon's steps, and re-discover their friend's discoveries.
